Fast & Flexible Chip Shooter DECAN F2 Service Manual
The head offset and camera offset is changed.
A pneumatic pressure difference occurred due to the damage of the coil tube.
Impact occurred to the ANC since the shutter opening and closing speed is too fast
(the nozzle is out of its position due to the impact).
Defective ANC movement since a chip entered the ANC.
Defective rotary joint connection (the Head# pneumatic pressure is low when
checking the pneumatic pressure level)
The nozzle is not properly mounted on the ANC.
Defective contact of CN6 and CN5 connectors in the Axis Sensor Board
(In the case of DECAN F2, SLM, SM471 and SM48X, the contact with the Conveyor
I/F Board and ANC sensor cable is defective.)
When the fiducial camera moves to the fiducial disk, it moved to the center of the
fiducial disk but the head failed to move to the center.
Defective ball spline
[How to Check]
1. Run the dialog box for pneumatic pressure diagnosis (check whether it is normal).
2. Clean and check the vacuum line at the head.
3. Check and replace the solenoid valve.
1. When the Z-axis moves down for automatic nozzle change, it collides with the
nozzle.
2. Set the R-axis of the nozzle holder again.
1. Check the rotary joint.
2. Check the ANC position.
3. Set the Z-axis offset in the system.
1. Perform calibration related to the head system.
2. Check the ANC position.
3. Set the Z-axis offset in the system.
1. Run the dialog box for pneumatic pressure diagnosis (check whether it is normal).
2. Check the head air module and tube for air leaks.
1. When operating the shutter manually, check the impact on the shutter.
2. Check and remove foreign materials in the ANC.
3. If the shutter speed is too fast, control it with the ANC Cylinder Speed Controller.
1. Run the dialog box for pneumatic pressure diagnosis (check whether it is normal).
2. Check the rotary joint.
1. Check the ANC nozzle setting.

Troubleshooting
1. Check the manual shutter movement.
2. Check the solenoid valve operation.
3. Check the contact of the Axis Sensor Board Connector.
4. Replace the Axis Sensor Board.
1. After thermal mapping, check whether the head is in normal state.
1. Inspect the corresponding spindle visually.
2. Check whether the spindle center is moved while turning the R-axis manually.
[Measures]
Clean the vacuum air line.
Perform calibration of the R-axis offset.
Perform Z-axis Offset and ANC Origin Z Offset.
Perform calibration of the ANC and head.
Perform calibration of the head.
Replace the coil tube.
Control the air supply quantity with the solenoid valve.
Clean the inside of the ANC.
Reassemble the rotary joint.
After rearranging the nozzles, operate the ANC normally.
Reconnect the CN6 and CN5 connectors in the Axis Sensor Board.
Perform thermal mapping.
Replace the damaged spindle and set the R offset and Z offset again.
E0E03 ANC Cannot open (close) the ANC shutter
[Cause]
Defective ANC Shutter Cylinder
Incorrect ANC Cylinder sensor position
Incorrect ANC fiducial mark position
Defective Nozzle Holder
Defective solenoid valve
Defective cylinder operation
[How to Check]
1. Check for the opening/closing of the ANC shutter.
2. Check the opening/closing speed of the ANC shutter (controlled with the Speed
Controller).

3. Check the operation of the ANC Shutter solenoid valve.
4. Check the ANC cylinder movement.
5. Check the position and operation of the ANC Cylinder Sensor.
1. Perform manual operation of the ANC.
2. Check for the opening/closing of the ANC shutter.
3. Check the position and operation of the ANC Cylinder Sensor.
1. Perform manual operation of the ANC.
2. Check the ANC fiducial mark position.
Check the nozzle holder visually using a camera.
1. Perform manual operation of the ANC.
3. Check for the opening/closing of the ANC shutter.
4. Check the opening/closing speed of the ANC shutter (controlled with the Speed
Controller)
5. Check the operation of the ANC Shutter solenoid valve.
6. Check the ANC cylinder movement.
7. Check the position and operation of the ANC Cylinder Sensor
[Measures]
Replace the ANC Shutter Cylinder.
Reassemble the ANC Cylinder Sensor.
Teach the ANC fiducial mark again.
Replace the nozzle holder.
Replace the solenoid valve.
After removing and disassembling the cylinder, control the inlet and outlet air flow
rate.
E0E04 Cannot mount a nozzle since there is no nozzle on the head
[Cause]
Vacuum pressure is high (200~350 mmHg when there is no nozzle).
When picking and placing a nozzle, the nozzle body is brightly reflected occasionally
due to the brightness of the outer LED.
Pneumatic pressure becomes high since the filter in the pneumatic line of the head is
assembled in the opposite direction.
There is interference between the opened ANC shutter and nozzle blade.
[How to Check]
1. Check the ANC nozzle setting.
